Is there a way to reconfigure the container just before the test execution?

Using an observer extension, i check each test method for a custom annotation that if exists i change the container descriptor in order to pass the annotation's elements as a configuration property that later will have to be used by the container to add a context parameter. But container reads the description once, at the startup.

And the two files are different. This is confusing. Which one is the "real" 1.0 xsd? If the other one can't be deleted in fear of breaking existing stuff using it, then perhaps a README file could be added under http://jboss.org/schema/arquillian/, which explains the difference between the two, and which one is preferred.
